I gvwvM/CW/ ARTHUR A. NgwTo/v Patented Sept. 12, 1939 UNITED STATE' eA'rENT orrlcs 4 Claims.

My present invention pertains to improvements in open nre place heating units and has for its primary object to provide a combination grate and hot-water heating unit that is adapted 5 to provide heat in the room where an open lire place is located and in addition, if desired may be arranged to convey hot-water heat to adjoining rooms or apartments.

Another object of my invention is the provision l0 of a re place unit that is adapted to be inserted or removed from the fire place when the occasion arises.

A further object of my invention is the provi-r sion of an extremely inexpensive re grate for heating fluid that is adapted for use particularly ln localities where standard or complete heating units are not constantly necessary, and the advantages of this particular invention are apparent when it is stated that in certain southern sections of the country or warmer climates the need for an economical and practical heating unit frequently arises only at night time, and when my fire grate is in operation gives the added feature of providing the user with an open re place in front of which he or she may sit.

A further object of the invention is the provision of my novel heating unit where no allowance in the construction of a building is made for housing a heating unit and hence my device may be installed in a building subsequent to the construction of same.

Other objects of the invention will be fully understood from the following description and claims when the same are read in connection with the drawing accompanying and forming part of this specification in which;

Figure l is a front elevational view of my novel grate per se.

Figure 2 is an end elevation of the grate.

Figure 3 is a sectional view taken in the plane on line 3--3 of Figure l and looking in the direction of the arrows.

Figure 4 is a sectional View taken in the plane indicated by the line 4 6 of Figure 2 and looking in the direction of the arrows.

Figure 5 is a top plan View of the grate.

Figure 6 is a. modied View of the water nipples of the grate and illustrating the arrangement of these nipples so as to present a more attractive appearance and also to accommodate the grate to varying conditions.

Figure '7 is a detailed view of the forward tubes of the grate construction shown in Figure 3, said view being partially fragmentary.

Similar numerals of reference designate corresponding parts in all of the views in the drawing, with exception to Figure 6 in which the modified construction is designated by other numerals.

My novel grate is removably adapted to be 5 arranged in a re place or mantel l, that is provided with the usual re box opening and the grate comprises at the rear thereof a water jacket 2 with the hot water inlet 3 positioned at the bottom thereof, and at this point I wish to 10 state that this inlet 3 also acts as a support or foot for the rear of the grate and normally rests on the floor of the lire box of the mantel. Mounted on the upper side and communicating directly with the jacket 2 is a hot water outlet 4. l5

My novel grate in addition to the elements just recited, comprises the hollow tubes 5 arranged on the upper end and forming an integral part of the grate, and these tubes 5 are in direct communication with the front tubes 6 that in turn 20 communicate directly with the downwardly depending tubes l, the downwardly depending tubes l in turn communicate with a longitudinal tube 8 and side tubes 8 and at this point I wish to have it understood that all of the tubes so far 25 referred to are of an equal diameter. However a deviation in the diameter of these tubes fairly falls within the scope of my invention.

Extending into the water jacket 2 and directly below the tubes 5 on the ends of the grate are a 30 transverse series of tubes 9 and these tubes at their forward ends enter the depending tubes 'l while transversely arranged in the lower end of the grate and in direct communication with the water jacket 2 and the lower forward tubes 8 are a 35 series of transverse tubes I0. Interposed between the forward tubes 6 and 8 and communicating with the depending tubes 'l are longitudinal tubes l I.

The front face of the jacket 2 is uted or 40 corrugated as at l2 and the purpose of this construction of the front face of the jacket is to hold the coal or other heating element away from the back of the grate so as to promote combustion, which would not be the case were the face l2 45 of a solid or smooth construction.

Manifestly I provide the legs i3 on the forward lower portion of the grate to act as a support in conjunction with the inlet pipe 3.

At this point I deem it proper to invite atten- 50 tion to the fact that the construction of tubes in direct communication with each other and likewise in communication with the water jacket assures a steady constant heat to the water that is circulating within the tubes and jacket. 55

Particular reference is now made to Figure 6 in which all of the construction is similar to the preferred construction with the exception that the inlet designated at 3' is curved to throw same at an angle with respect to the Water jacket 2 and hence present a more or less hidden appearance. In addition the outlet 4 is positioned directly in back, in the center of the Water jacket instead of on top as shown in the preferred construction and this provision is made for the same reason as the provision of the inlet 3' in order to accommodate the device to varying conditions and present a more finished appearance.

The simple construction of my device is an assurance of the inexpensive cost of production, installation and operation, and I Wish it distinctly understood that any type of fuel may be employed as a heating element Where such fuel is more accessible than coal or the like.

What I claim is:

1. A heating grate comprising a Water jacket, a plurality of pipes forming the bottom, sides, front and corner posts; of the heating grate, said plurality of pipes connected to each other and to the Water jacket, the plurality of pipes being in uninterrupted circulatory communication with each other and with the Water jacket, some of said side pipes at one end being spaced a greater width from the remaining pipes.

2. A heating grate comprising a water jacket, a plurality of pipes forming the bottom, sides, corner posts and front of the grate, said plurality of pipes connected to each other and to the Water jacket, the top of the post being connected to the water jacket adjacent the top, said plurality of pipes being in uninterrupted circulatory communication with each other and with the Water jacket, some of said side pipes being curved and at one end spaced a greater Width from the remaining pipes,

3. A heating grate comprising a water jacket having inlet and outlet means, vertical pipes forming corner posts for said grate, a plurality of pipes forming a bottom, sides and front for said grate, the plurality of side pipes connected to the corner posts and to the water jacket, the plurality of pipes forming the bottom of the grate connected to the lower front pipe and the water jacket, the upper portion of the front of said grate being in direct circulatory communication with the upper portion of the Water jacket, all of said pipes being in uninterrupted circulatory communication with each other and with the water jacket.

4. A heating grate comprising a water jacket having inlet and outlet means, vertical pipes forming corner posts for said grate, a plurality of pipes forming a bottom, sides and front for said grate, the plurality of side pipes connected to the corner posts and to the Water jacket, the plurality of pipes forming the bottom of the grate connected to the lower front pipe and to the Water jacket, the upper pipe of each of said sides of the grate being in direct circulatory communication with the upper portion of the water jacket,

all of said pipes being in uninterrupted circulatory communication with each other and with the Water jacket.
